19241 NAKAI, LIGNEOUS PLANTS OF EASTERN ASIA 75 



This Oak is allied to Quercus serrata Thunb. (Q. acutissima Carruth.) 

 but the leaves are glabrous from the beginning, the cupules and acorns are 

 smaller and the involucral bracts are slenderer and shorter. The wood 



is used for the teeth of hulling mortars, for the spokes and the outer rim 

 of wheels,

This species is nearest to Quercus Gilliana Rehd. & Wils. and Q. phil- 

 lyraeoides A. Gray but by its mode of serration it is readily distinguishable 

 from related species. There is one undeveloped fruit by which I could 

 ascertain that the acorn of this Oak ripens the second year as in Quercus 

 phillyraeoides.

This is nearest to Quercus phillyraeoides A. Gray which differs chiefly 

 in the glabrous under side of the leaves. Wright's specimen has the leaves 

 tomentose beneath and resembles some forms of Quercus suber L., but 

 Wilson's specimen has the leaves less densely pubescent. Quercus phiU
